The PMAG 20 LR/SR GEN M3 brings many of the M3 improvements to the 20-round 7.62 NATO/.308 Winchester SR-25 magazine form factor and replaces the previous generation MAG243 in the Magpul line. We then insert a block inside the spring to limit capacity to 10 rounds without impacting the spring rate, preserving function and reliability. The floorplates are then attached using an ultrasonic welder and a toughened adhesive designed to withstand heat and shock, preventing disassembly and reversal of the modification.
The 7.62x51 NATO (.308 Winchester) PMAG 20 LR/SR GEN M3 is a lightweight, cost effective, high reliability magazine for SR25/M110 pattern rifles featuring constant-curve body, anti-tilt follower, and snap on Impact/Dust Cover. Designed specifically for military-issue MK11/M110 rifles and SAAMI-spec ammunition, the PMAG 20LR/SR is less than half the weight of standard issue steel magazines and maintains a service life round count approximately equal to the rifle barrel itself.
Made in U.S.A.
